MOP HEAD AND WRINGER.

To all whom it may concern:

Be it known that I, CARL H. LIEN, a citizen of the United States ofAmerica, residing at Columbus, in the county of Ward and State of NorthDakota, have invented new and useful Improvements in Mop Heads andWVringers, of which the following is a specification.

This invention relates to mop heads and wringers, and an object of theinvention is to provide a novel device of this character which islocated at one end of the handle and designed to receive the mop clothand to hold it securely between a pair of relatively movable wringingrollers which are so constructed that they may be operated to wring thecloth obviating the necessity of causing the hands of the operator to bebrought into direct contact therewith and thus greatly facilitating thelabor at this end.

In the drawing, forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several views:-Figure 1 is a front elevation of my improved mop head and wringer.Fig. 2 is an end view thereof. Fig. 3 is a detail section taken on theline 33 of Fig. 2.

My improved mop head and wringer consists of a handle 1 on which ismounted a head member 2 Whose end portions are formed to providebrackets 3 in which the trunnions 4 of a wringing roller 5 arejournaled. An auxiliary head member 6 is slidably mounted on the handleand it is formed to provide brackets 7 which are disposed outwardly ofthe brackets 3. The brackets 7 have their extremities extended beyondthe extremities of the brackets 8, and as illustrated, these bracketsare formed to provide perforations 8 for the reception of the crankhandle 9and trunnion 10 respectively of the roller 11. The roller isprovided with a squared socket for receiving the correspondingly formedportion 12 of the crank handle. The portion 12 of the crank handle isextended beyond one of the brackets 7 and formed therein with a seriesof notches 13 for receiving a spring tension sliding dog 14.

The dog 14 is designed to engage either of the notches for two purposes,first, as a means of holding the crank handle operatively engaged withthe roller and as means Specification of Letters Patent.

for preventing rotation of the roller during the mopping operation. Thedog 14 is mounted so that it can be manually rotated and moved intoengagement with an annular groove 15 in the portion 12 of the crankhandle. This construction is such that when it is desired to wring thecloth the dog can be moved into the groove 15 and the crank handlerevolved to permit the cloth to be fed between the rollers as will beunderstood. In order that the rollers will be revolved in oppositedirections simultaneously I provide a helical spring 16 which isconfined between the head members 2 and 6, the said spring beingdesigned to exert its tension against the head member 6 so as to tendnormally to move the roller 11 into frictional contact with itscompanion roller 5. The cloth 17 is of belt form. Incident to thepeculiar construction of the crank handle and the engagement therewithof the hereinbefore described locking dog the latter can be disengagedfrom the former to permit the operator to entirely remove the crankhandle from the roller so as to permit adjustment of the latter betweenthe brackets 7 to facilitate the insertion or removal of the mop cloth.

The brackets 3 are provided with guide pins 18 which extend throughlongitudinal guide slots 19 in the brackets 7. The arrangement of thehead member 6 on the handle is such that it can be moved convenientlyagainst the tension of the spring 16 during the insertion or removal ofthe cloth.

I claim lJA combined mop head and wringer comprising revolubly mountedrollers mounted for relative movement toward or away from each other, acrank handle removably engaged with one of the rollers, supports for therollers, and means operable to engage the crank handle to hold the sameagainst rotary movement.

2. A combined mop head and wringer comprising companion relativelymovable head members, rollers supported by the said head members, aspring confined between the head members and exerting its tensionthereagainst to hold the rollers yieldingly engaged with each other, acrank handle removably engaged with one of the rollers and supported byone of the head members, and means for engaging the crank handle to holdthe same operatively associated with the roller and to hold the rolleragainst rotation.

3. A combined mop head and wringer comprising relatively movable headmembers, a handle supporting the said members, rollers supported by thehead members, a crank handle supported by one of the head members andremovably engaged with one of the rollers, a locking dog operable toengage the crank handle to hold the same against rotary movement, andmeans on the crank handle adapted to be engaged by the locking dog topermit rotation of the said handle.

4. A combined mop head and wringer comprising a handle, a head memberfixed to one end of the handle, a movable head member slidably mountedon the handle and on the fixed head member, a spring exerting itstension between the said head members, a roller supported by the fixedhead member, a roller supported by the movable head member, and a crankhandle removably supported by the said movable head member and removablyengaged with the roller of such head member;

In testimony whereof I aflix my signature in presence of two witnesses.

CARL H. LIEN.
